Chuck,

	Re your request about adding bank select to ZCPR3, I feel that
bank select has to be implemented in the BDOS/ZRDOS rather than in Z3 itself,
altho ZCPR3 CP could use it.  We (ie, the Echelon effort) are not moving
in that direction, but rather in the direction of the Z800.  The Z800
offers a large memory address space, Z80 compatability, a higher speed,
and other nice features, and ZRDOS3 combined with a ZCPR3 for it are
on the drawing boards, with CP/M compatability be retained (hopefully
entirely, but the Z3 approach may have to be changed - still formulating).
Part of the Z80 compatability involves dividing memory into 64K banks,
so bank switching definitely comes into play with ZRDOS3/ZCPR3.

	I have no idea when this software will emerge.  ZRDOS1 is out now,
and ZRDOS2 is almost out (both are for conventional CP/M environs, tho).
